Geomagnetic storm conditions are expected on Saturday night, likely pulling the northern lights further south below the Canadian border, according to a National Oceanic and Atmospheric Administration forecast. (Here’s an updated forecast for Sunday night.)

Displays of Northern lights are possible on Sunday night across the Northern U.S. due to a geomagnetic storm underway.

Auroral activity may be seen below the Canadian border on Tuesday night, and there’s a chance the northern lights will become more visible in the coming days as geomagnetic storm conditions likely increase, according to a National Oceanic and Atmospheric Administration forecast.

It is “likely” that the Northern Lights could be snapped in Wiltshire’s skies tonight after an amber alert was issued. AuroraWatch UK, a service provided by physicists from Lancaster University, issued an amber alert shortly before 5.
